  • COAGULATION AND FLOCCULATION MRWA

    Coagulation and flocculation occurs in successive steps, allowing particle collision and growth of floc. This is then followed by sedimentation (see Sedimentation Chapter). If coagulation is incomplete, flocculation step will be unsuccessful, and if flocculation is incomplete, sedimentation will be unsuccessful. COAGULATION

    Even after coagulation and flocculation, sedimentation does not remove enough suspended impurities from water to make it crystal clear. The remaining nonsettling floc causes noticeable turbidity in the water and can shield microbes from disinfection. Filtration is a physical process that removes

    Mar 19, 2019· What is Flocculation in Water Treatment? Flocculation is the phase that occurs after flash mixing. During this phase, the particles to be removed from water are brought to larger agglomerations, called flocs, in order to settle down in the sedimentation chamber and be easily filtered.This happens thanks to the reaction with a polymer solution, which acts as flocculant agent.
